Ok, I'm worried.
Since so many of the computers in my school have viruses, my USB picked one up,
autorun.inf. I've formatted my USB a couple of times already and it still says it has it, I even formatted using a Mac computer, but it's still there.
My uncle says my entire computer system must be the one that's infected now, but I searched using command prompt and I don't seem to see it in there.

So is it just my USB that's screwed up? And how do I get rid of it from there? I don't know what else to do besides formatting it.
